Stencil device with means to clean

ABSTRACT

A machine is disclosed for manufacturing finished wall panels. The machine is made up of a rigid fixed frame provided with a water tank at the center. Stencils are hinged to the frame at the edge of the water tank to swing from a position over wall supporting panels to be manufactured to a position in the tank to be washed. The stencils may be made of a rigid material such as one-eighth inch steel cut out in the form of the pattern desired on the article to be prepared. When the stencils are swung down over a panel, such as a 4 X 8 piece of plywood, the stencil rests on the plywood. Thus a plaster material may be sprayed over the stencil and into the spaces between the pattern and the stencil may then be swung up into the tank leaving a brick panel where the margins of the cutout portions forming simulated plaster joints and the excess plaster may be washed off in the tank of water.

ABSTRACT 6 Claims, 3 Drawing Figures STENCIL DEVICE WITH MEANS TO CLEAN OBJECTS OF THE INVENTION It is an object of the invention to provide an improved machine for manufacturing wall panels.

Another object of the invention is to provide an improved machine for forming patterns in coatings.

Another object of the invention is to provide a machine that is simple in construction, economical to manufacture, and simple and efficient to use.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a stencil supported on a wall with cutout portions in the form of a pattern according to the invention.

FIG. 2 is a view of another embodiment of the invention.

FIG. 3 is a view of yet another embodiment of the invention.

DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular reference to the drawings, a rigid frame is shown which may be in the form of an A-frame having members 11 welded at their bottom to the upper edges of the tank 13. A top 12 is welded to the apex of the A-frame and longitudinal members connect the A-frames. Pulleys 21 and 22 are supported on the longitudinal members. The stencils 24 and 25 are hinged to the top of the water tank at 17 and 18 respectively. The panels supporting the frame are welded to the edges of the tank below the hinges. The stencils may be swung upward by the cords 19 and 20 which are supported on the pulleys 21 and 22 and the cords 19 and 20 may be suitably counterweighted. Thus, when it is desired to form a coating on a panel, the panel is laid on the frame 14 or and the stencils 24 and 25 are swung down into position on the panel and clamped to the panel. The plaster material is then sprayed over the stencil so that it coats the panel in the spaces cut out on the stencil. The stencil is then unclamped and pulled up by means of the cords l9 and and swung into the water in tank 13 where it may be washed.

While the panel on frame 14 is being sprayed, another panel can be placed in position on the frame 15 and the stencil 24 washed. Then while the stencil 25 is being washed, the stencil 24 may be used for spray coating another panel at the same time.

In the embodiment of the invention shown in FIG. 2, the stencils 124 and 125 and the stencils 126 and 127 are hinged to the tank 113, which may contain water to wash the stencils. Suitable frames will be provided to support panels to be coated. The stencils 124 and 125 may be, for example, 4 X 10, while the stencils 126 and 127 may be, for example, 4 X 8, or any other combination of lengths can be made. The stencils in FIG. 2 may be used in the same manner as the stencils in FIG. 3.

FIG. 1 shows a wall 214 which may be supported at right angles to the wall 215. Stencil 224 may be supported on the wall by means of screws or other fasteners indicated at 226. The stencil will have cutout portions 227 and 228, for example, into which the plaster material may be sprayed. The stencil may then be removed from the fasteners 226, leaving the desired pattern on the wall.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
